  • Publication number: 20120015353
    Abstract: The present invention relates to a novel method for analyzing nucleic acid sequences based on real-time detection of DNA polymerase-catalyzed incorporation of each of the four nucleotide bases, supplied individually and serially in a microfluidic system, to a reaction cell containing a template system comprising a DNA fragment of unknown sequence and an oligonucleotide primer. Incorporation of a nucleotide base into the template system can be detected by any of a variety of methods including but not limited to fluorescence and chemiluminescence detection. Alternatively, microcalorimetic detection of the heat generated by the incorporation of a nucleotide into the extending template system using thermopile, thermistor and refractive index measurements can be used to detect extension reactions.

  • Publication number: 20110301042
    Abstract: The invention generally relates to methods for sequencing a plurality of nucleic acids from different samples. In certain embodiments, methods of the invention provide contacting a nucleic acid duplex including a primer nucleic acid hybridized to a template nucleic acid with a polymerase enzyme in the presence of a first detectably labeled nucleotide under conditions that permit the polymerase to add nucleotides to the primer in a template-dependent manner, in which a unique oligonucleotide sequence is attached to the template nucleic acid so that the template nucleic acid may be differentiated from other template nucleic acid molecules, detecting a signal from the incorporated labeled nucleotide, and sequentially repeating the contacting and detecting steps at least once, wherein sequential detection of incorporated labeled nucleotide determines the sequence of the nucleic acid.

  • Publication number: 20110027790
    Abstract: The disclosure provides methods of reducing the range of representation levels of nucleic acid targets. The methods are particularly useful for multi-target analyses benefiting from a low variance of target representations, such as, e.g., single molecule sequencing and/or heterozygous genotyping, and pathogen diagnosis. Two general methods are provided. In Method 1, starting concentrations of probes are adjusted. In Method 2, target-specific probes are “binned,” i.e., several subsets of probes are selected based on similar representation levels. Thereafter, each subset of corresponding targets is extracted, with or without amplification, using a separate portion of the sample (i.e., separate vessels).

  • Publication number: 20100304447
    Abstract: The disclosure provides methods of generating paired reads in sequencing-by-synthesis process, particularly, in systems with relatively short read lengths (e.g., 15-35 bases), such as for example, in single molecule sequencing by synthesis. Several implementations of the methods are provided. Of particular advantage are the methods that permit re-sequencing of the template, which yields lower error rates. The invention further provides methods of using paired reads, for example, for positioning them over repeats or for assembly into large sequences, including whole genome assembly.
